.SH DESCRIPTION
.LP
The \fBvi\fR (visual) utility is a display-oriented text editor based on an
underlying line editor \fBex\fR. It is possible to use the command mode of
\fBex\fR from within \fBvi\fR and to use the command mode of \fBvi\fR from
within \fBex\fR. The visual commands are described on this manual page; how to
set options (like automatically numbering lines and automatically starting a
new output line when you type carriage return) and all \fBex\fR line editor
commands are described on the \fBex\fR(1) manual page.
.sp
.LP
When using \fBvi\fR, changes you make to the file are reflected in what you see
on your terminal screen. The position of the cursor on the screen indicates the
position within the file.
.sp
.LP
The \fBview\fR invocation is the same as \fBvi\fR except that the
\fBreadonly\fR flag is set.
.sp
.LP
The \fBvedit\fR invocation is intended for beginners. It is the same as
\fBvi\fR except that the \fBreport\fR flag is set to \fB1\fR, the
\fBshowmode\fR and \fBnovice\fR flags are set, and \fBmagic\fR is turned off.
These defaults make it easier to learn how to use \fBvi\fR.
.SH OPTIONS
.LP
The following options are supported:
.SS "Invocation Options"
.LP
The following invocation options are interpreted by \fBvi\fR (previously
documented options are discussed under NOTES):
.sp
.ne 2
.na
\fB\fB\(mi\fR | \fB-s\fR\fR
.ad
.RS 25n
Suppresses all interactive user feedback. This is useful when processing editor
scripts.
.RE

.sp
.ne 2
.na
\fB\fB-C\fR\fR
.ad
.RS 25n
Encryption option. Same as the \fB-x\fR option, except that \fBvi\fR simulates
the \fBC\fR command of \fBex\fR. The \fBC\fR command is like the \fBX\fR
command of \fBex\fR, except that all text read in is assumed to have been
encrypted.
.RE

.sp
.ne 2
.na
\fB\fB-l\fR\fR
.ad
.RS 25n
Sets up for editing \fBLISP\fR programs.
.RE

.sp
.ne 2
.na
\fB\fB-L\fR\fR
.ad
.RS 25n
Lists the name of all files saved as the result of an editor or system crash.
.RE

.sp
.ne 2
.na
\fB\fB-r\fR \fIfilename\fR\fR
.ad
.RS 25n
Edits \fIfilename\fR after an editor or system crash. (Recovers the version of
\fIfilename\fR that was in the buffer when the crash occurred.)
.RE

.sp
.ne 2
.na
\fB\fB-R\fR\fR
.ad
.RS 25n
\fBReadonly\fR mode. The \fBreadonly\fR flag is set, preventing accidental
overwriting of the file.
.RE

.sp
.ne 2
.na
\fB\fB-S\fR\fR
.ad
.RS 25n
This option is used in conjunction with the \fB-t\fR \fItag\fR option to tell
\fBvi\fR that the tags file can not be sorted and that, if the binary search
(which relies on a sorted tags file) for \fItag\fR fails to find it, the much
slower linear search should also be done. Since the linear search is slow,
users of large tags files should ensure that the tags files are sorted rather
than use this flag. Creation of tags files normally produces sorted tags files.
See \fBctags\fR(1) for more information on tags files.
.RE

.sp
.ne 2
.na
\fB\fB-t\fR \fItag\fR\fR
.ad
.RS 25n
Edits the file containing \fItag\fR and position the editor at its definition.
It is an error to specify more than one \fB-t\fR option.
.RE

.sp
.ne 2
.na
\fB\fB-v\fR\fR
.ad
.RS 25n
Starts up in display editing state, using \fBvi\fR. You can achieve the same
effect by typing the \fBvi\fR command itself.
.RE

.sp
.ne 2
.na
\fB\fB-V\fR\fR
.ad
.RS 25n
Verbose. When \fBex\fR commands are read by means of standard input, the input
is echoed to standard error. This can be useful when processing \fBex\fR
commands within shell scripts.
.RE

.sp
.ne 2
.na
\fB\fB-w\fR\fIn\fR\fR
.ad
.RS 25n
Sets the default window size to \fIn\fR. This is useful when using the editor
over a slow speed line.
.RE

.sp
.ne 2
.na
\fB\fB-x\fR\fR
.ad
.RS 25n
Encryption option. When used, \fBvi\fR simulates the \fBX\fR command of
\fBex\fR and prompts the user for a key. This key is used to encrypt and
decrypt text using the algorithm of the \fBcrypt\fR command. The \fBX\fR
command makes an educated guess to determine whether text read in is encrypted
or not. The temporary buffer file is encrypted also, using a transformed
version of the key typed in for the \fB-x\fR option. If an empty encryption
key is entered (that is, if the return key is pressed right after the prompt),
the file is not encrypted. This is a good way to decrypt a file erroneously
encrypted with a mistyped encryption key, such as a backspace or undo key.
.RE

.sp
.ne 2
.na
\fB\fB-\fR\fIcommand\fR | \fB-c\fR \fIcommand\fR\fR
.ad
.RS 25n
Begins editing by executing the specified editor \fIcommand\fR (usually a
search or positioning command).
.RE

.SS "/usr/xpg4/bin/vi and /usr/xpg6/bin/vi"
.LP
If both the \fB-t\fR \fItag\fR and the \fB-c\fR \fIcommand\fR options are
given, the \fB-t\fR \fItag\fR option is processed first. That is, the file
containing \fItag\fR is selected by \fB-t\fR and then the command is executed.
.SH OPERANDS
.LP
The following operands are supported:
.sp
.ne 2
.na
\fB\fIfilename\fR\fR
.ad
.RS 12n
A file to be edited.

.SH COMMAND SUMMARY
.LP
The \fBvi\fR command modes are summarized in this section.
.SS "vi Modes"
.ne 2
.na
\fBCommand\fR
.ad
.RS 13n
Normal and initial mode. Other modes return to command mode upon completion.
\fIESC\fR (escape) is used to cancel a partial command.
.RE

.sp
.ne 2
.na
\fBInput\fR
.ad
.RS 13n
Entered by setting any of the following options:
.sp
.in +2
.nf
a A i I o O c C s S R
.fi
.in -2
.sp

Arbitrary text can then be entered. Input mode is normally terminated with the
\fIESC\fR character, or, abnormally, with an interrupt.
.RE

.sp
.ne 2
.na
\fBLast line\fR
.ad
.RS 13n
Reading input for \fB: / ?\fR or \fB!\fR. Terminate by typing a carriage
return. An interrupt cancels termination.

the word that would be moved over. Double the operator, for example \fBdd\fR,

\fISolaris Advanced User\&'s Guide\fR
.SH AUTHOR
.LP
\fBvi\fR and \fBex\fR were developed by The University of California, Berkeley
California, Computer Science Division, Department of Electrical Engineering and
Computer Science.
.SH NOTES
.LP
Two options, although they continue to be supported, have been replaced in the
documentation by options that follow the Command Syntax Standard (see
\fBIntro\fR(1)). An \fB-r\fR option that is not followed with an
option-argument has been replaced by \fB-L\fR and \fB+\fR\fBcommand\fR has been
replaced by \fB-c\fR \fBcommand\fR.
.sp
.LP
The message \fBfile too large to recover with\fR \fB-r\fR \fBoption\fR, which
is seen when a file is loaded, indicates that the file can be edited and saved
successfully, but if the editing session is lost, recovery of the file with the
\fB-r\fR option is not possible.
.sp
.LP
The editing environment defaults to certain configuration options. When an
editing session is initiated, \fBvi\fR attempts to read the \fBEXINIT\fR
environment variable. If it exists, the editor uses the values defined in
\fBEXINIT\fR; otherwise the values set in \fB$HOME/.exrc\fR are used. If
\fB$HOME/.exrc\fR does not exist, the default values are used.
.sp
.LP
To use a copy of \fB\&.exrc\fR located in the current directory other than
\fB$HOME\fR, set the \fIexrc\fR option in \fBEXINIT\fR or \fB$HOME/.exrc\fR.
Options set in \fBEXINIT\fR can be turned off in a local \fB\&.exrc\fR only if
\fIexrc\fR is set in \fBEXINIT\fR or \fB$HOME/.exrc\fR. In order to be used,
\fI\&.exrc\fR in \fB$HOME\fR or the current directory must fulfill these
conditions:

Tampering with entries in \fB/usr/share/lib/terminfo/?/*\fR or

problems.
